The old covering is partly stripped. A penetration is unfinished. Rain is approaching. Your roofing bad weather plan must tell the supervisor when to stop, what can still be protected safely, and when everyone must withdraw.
Make the decision while the exit route is clear. Once a cover starts moving or the roof turns slick, the choices get worse.
Build the roofing bad weather plan before mobilization
Write the plan for the roof and scope in front of you. Do not copy a generic wind or rain limit onto every work order.
A repair with no exposed deck has a different shutdown problem from a re-roof with open junctions, stored material and occupied rooms below. The work stage controls the exposure.
Name the people who can make each call
Put a name or role beside each decision:
- delay or cancel mobilization
- open the planned roof section
- stop production
- direct a controlled shutdown
- order immediate withdrawal
- inspect the site after the event
- approve the restart
One supervisor may hold several roles. Write them down anyway. The crew should not have to phone around while weather reaches an open section.
Give the site supervisor authority to stop production. Immediate danger needs an even simpler instruction: withdraw first and report the condition from the location named in the job plan.
Before mobilization, find the occupational health and safety regulator that covers the job location. Record the applicable official rule or guidance page, the date checked and the decision made for the site plan. Do not treat a generic weather limit as approval for a roof-specific trigger.
Map the stages that expose the building
Break the scope into work stages. Mark when each stage could expose deck, underlayment, valleys, ridges, penetrations, wall junctions, drainage paths or rooms below.
For every stage, complete one control row. Record the section opened, exposure created, protection method, assigned workers, materials staged and clear withdrawal route. Do not open that section until every field has an answer.
Opening less roof is often the cleanest control. Limit each section to what the crew can complete, protect and withdraw from during the planned work window. Use the stage control row to make that limit visible to the supervisor and crew.
Set a trigger for each response level
Set the triggers from the roof, work stage, product instructions, equipment instructions and official safety guidance for the job location. Do not copy a weather limit from another site.
For every hazard, write an observable condition and the required action. If the forecast worsens, review the opening plan. If the crew still has safe footing and time to cover the opening, shut down. If footing, access or the exit route is lost, withdraw.
Use the same method for rain, hail, snow, ice, wet or frosted surfaces, changing wind, nearby lightning and blocked drainage. The action must be clear: check again, stop and secure, or withdraw now.
State the next review time so the forecast does not get forgotten after production starts.
Run the roofer weather checklist before opening the roof
Check the forecast. Then check the site. These are separate decisions and separate records.
A forecast record shows what information was available when the call was made. A site observation shows what the supervisor could actually see and feel at the job.
Record the forecast and work window
Use Environment and Climate Change Canada (opens in a new tab) for the official Canadian forecast and alert information. Record the location selected, issue time, time checked, information reviewed, planned work window and next review time.
Name the person who made the mobilization decision. If the forecast changes, add another entry. Keep the earlier entry intact.
Inspect the work area and the area below
Walk the roof, access route and ground before stripping starts. Check footing, edges, access equipment, drainage paths, stored materials and the section to be opened.
Look below the planned work. Record occupied rooms, equipment, finished surfaces and any place where water could appear. Identify the last practical point where the crew can stop without creating another opening.
Read the instructions for roofing products, access equipment, tools, temporary covers and restraints. Check substrate condition, storage, attachment and exposure instructions. Change the work stage or hold the work when the planned method does not fit those instructions.
Stage protection before it is needed
Put covers, fasteners, restraints, water-control materials and communication equipment where designated workers can reach them. Do this before opening the roof.
Walk the withdrawal route. Clear pallets, cords, packaging, waste and removed material. Confirm that the crew can reach the assembly point or protected location named for the hazard.
Add these fields to the job record before work starts. The work order template gives you a practical base for the assigned crew, scope, site notes and attachments.
Run the roofing site shutdown in one clear order
Stop production first. Securing the building comes second, and only while the planned method remains safe.
If the condition calls for immediate withdrawal, skip the protection and material-control steps. Send the crew to the named location and account for everyone there.
Stop work and complete the first headcount
Stop stripping, cutting, fastening and installation. Do not push for one more course, another sheet or the fifth penetration.
Count the crew and withdraw everyone who is not assigned to the controlled shutdown. Keep people clear of areas below loose material or possible water entry.
The supervisor then decides whether designated workers can still reach the unfinished section with stable footing, visibility, access and a clear exit route.
Protect only what remains safely reachable
Cover reachable openings using the method written for the job. Keep drainage paths open. Watch where the cover sends water rather than looking only at whether it covers the opening.
Temporary protection can reduce exposure. It does not promise a watertight building.
If a cover starts moving while packaging, tools or removed material remain near the edge, reassess immediately. Do not chase moving items. Restrain or remove only material that remains safely reachable.
Abandon the task when control is lost
Leave unfinished protection when footing, access, visibility, material control or the exit route becomes unsafe. Do not send someone back for a tool, close photograph or loose piece of material.
Complete the final headcount at the location named in the plan. Record any opening, material, cover or tool left unfinished or unsecured.
From a safe position, check accessible internal areas. Move occupants away from visible water entry. Handle affected cords, tools and electrical equipment through the job’s safety process before reuse.
Take wide photographs. Show the roof section, direction and work stage. Label the time and observed condition. A tight photograph of wet material is weak evidence when nobody can tell where it was taken.
Keep roof weather delay records that explain the decision
“Rain delay” is not a useful site note. Record what information was available, what the supervisor observed, what stopped and what remained exposed.
Keep these fields together:
- official forecast location, issue time and check time
- observed condition and observation time
- trigger and decision
- production stop time
- work stage and exposed sections
- first and final headcounts
- designated shutdown workers
- covers fixed and openings left exposed
- loose material removed and material left behind
- customer notice and next review time
- labelled photographs
Write facts. “Water visible below the unfinished east junction” can be checked. “The whole ceiling is damaged” cannot be supported until that area has been inspected.
If an incident may require a safety notification, check the official reporting page of the occupational health and safety regulator for the job location. Send worker-coverage and claim questions to the provincial or territorial workers’ compensation board. Record each decision in the job file.
Split the event into plain cost buckets
Use separate cost tracking buckets for ordinary production labour, shutdown labour, temporary protection, inspection work and remobilization. Separate accepted-scope materials from covers, fasteners or other materials used only because of the event.
These records show what happened and what it cost your business. Check the accepted contract and the consumer or construction requirements for the province or territory before deciding whether added work changes the price. Use the official provincial or territorial government site to identify the body responsible for that contract question, then ask that body.
If weather damage becomes a separate repair rather than part of the accepted scope, inspect it before pricing it. Use the roof leak repair quote guide to separate investigation, repair scope, exclusions, labour and materials.
Notify the customer without promising an unchecked restart
Tell the homeowner, property manager or general contractor that production stopped. Identify the open section, the protection completed, anything left unfinished and the time of the next review.
Do not say concealed areas are dry unless they have been inspected. Do not give a new completion date before checking the roof, access, products, internal areas and remaining work sequence.
Keep the event note separate from the change order
A weather event record documents the interruption. It does not by itself change the accepted scope, price or completion date.
Read the accepted contract and check the provincial or territorial requirements that govern the job before changing the schedule or invoice. If inspection shows work outside the accepted scope, define it and obtain any approval required by the contract or those requirements before proceeding. Immediate safety work may need a different documented response.
The house example is electrical, but the document boundary is the same. For R. Chen at 14 Oak Street, Quote Q-1847 was 1,105. The lined ceiling meant extra cable and chasing were approved on site as a 160 change order. Invoice INV-1847 was 1,265. These are sample currency units, not roofing rates. The site condition explained why the work changed. The change order approved the addition.
Use the guide to writing a clear quote when added work needs a defined scope, exclusions, price and acceptance record.
For approved added work, use the Canada Revenue Agency’s GST/HST guide for registrants (opens in a new tab) to determine the tax treatment. Record the treatment used on the change order and invoice.
Decide whether the roof is safe to enter before inspecting it
Do not send someone onto the roof just because the rain stopped. From a safe location, assess the access route, visible roof conditions, temporary covers, weather information and any sign of movement or water buildup.
Name the person allowed to make the re-entry decision. Record the time, visible conditions and decision. If safe access cannot be established, keep the roof closed to workers and plan another review.
Inspect, cost and approve the work before restarting
Once safe re-entry is authorized, inspect before approving production. Check damage and products, define the remaining or added work, record actual costs and forecast job costs using your own figures, obtain any required change-order approval, then record safe restart approval.
Check access, footing, roof edges, drainage, temporary covers, stored materials, tools and affected internal areas. Record who inspected them and when.
Decide what happens to exposed products
Inspect installed and stored products. Record wet products found. State which products can remain, need further inspection, require removal or need manufacturer guidance.
Check temporary protection before removing it. Look for trapped water, movement, failed attachment and redirected drainage. Plan the removal so it does not expose more roof than the crew can control.
Define and cost the next work stage
Write the remaining sequence again. State which section opens first, what must be dried or removed, where protection will sit and when the next weather review occurs.
Separate remaining accepted-scope work from added work awaiting approval. Record actual labour and materials already used. Forecast the labour, materials and remobilization still needed using your own figures.
Do not treat safe restart approval as approval to perform or charge for added work. Record the required commercial approval separately, then brief the crew on changed hazards, assigned tasks and the withdrawal route.
Add a compact roof-weather attachment to the work order
Use the main work order for the crew, scope and site notes. Add this short attachment for the weather decisions that can otherwise disappear between photographs, messages and time entries.
